The Hydraforce CV42-M20-0-N-15 (5204101) is a screw-in, cartridge-style hydraulic check valve designed primarily for use as a blocking or load-holding device in hydraulic systems. This model facilitates flow from port 1 to port 2, while typically blocking flow in the reverse direction, ensuring efficient operation and system safety. The valve features a fully guided poppet that remains spring-biased in the closed position until enough pressure is exerted at port 1 to open it towards port 2. Constructed with a hardened seat, the CV42-M20-0-N-15 offers extended service life and minimal leakage, crucial for maintaining system integrity and performance. It is equipped with optional bias springs which provide additional flexibility for backpressure applications, enhancing its utility across various hydraulic setups. The valve conforms to ISO 7789 cavity specifications, ensuring broad compatibility with standard hydraulic systems. Key performance ratings include a pressure rating of up to 3500 psi (241 bar), and it accommodates a wide range of operating temperatures depending on the seal material used: from -40°C to +100°C with Buna N seals, -26°C to +204°C with Fluorocarbon seals, and -54°C to +107°C with Polyurethane and Urethane seals. The CV42-M20-0-N-15 also boasts robust corrosion protection with up to 960 hours of salt spray resistance per ASTM B117. The valve's internal wetted surface area measures approximately 297 cm² (46 in²), and it features a compact unit weight of 0.62 kg (1.36 lb). Installation specifications include a VC42M2 cavity type without any orientation restrictions and a cartridge installation torque requirement between 149 to 176 Nm (110 to 130 ft-lb). For maintenance or repairs, various seal kits are available including options for Buna N, Fluorocarbon, Polyurethane, and Urethane materials.
